Central venous occlusion (CVO) or stenosis (CVS) is a common complication of long-term hemodialysis catheters. Endovascular intervention, primarily balloon angioplasty and occasionally stent placement, is the primary approach for managing CVS/CVO lesions. The presence of a filter within the inferior vena cava (IVC) lumen makes recanalization of the IVC more challenging. Here we present a complex case of a 47-year-old female with end-stage kidney disease (ESKD), systemic lupus erythematosus, and recurrent deep venous thrombosis, necessitating an IVC filter, who became catheter-dependent via the right femoral vein and presented with total IVC occlusion below the filter. The occlusion was managed successfully with sequential angioplasty and stenting of the stenotic lesions. This intervention restored venous flow through the IVC into the right atrium and maintained dialysis access through the catheter. This case underscores the complexity of managing CVS/CVO in dialysis patients, especially with the presence of filters within the vascular dialysis conduit.
中心静脉闭塞(CVO)或狭窄(CVS)是长期血液透析导管的常见并发症。血管内介入治疗,主要是球囊血管成形术,偶尔进行支架置入,是处理CVS/CVO病变的主要方法。下腔静脉(IVC)管腔内存在滤器使得IVC再通更具挑战性。在此,我们报告一例复杂病例,一名47岁女性,患有终末期肾病(ESKD)、系统性红斑狼疮和复发性深静脉血栓形成,需要置入IVC滤器,通过右股静脉建立了长期导管依赖,且在滤器下方出现了IVC完全闭塞。通过对狭窄病变依次进行血管成形术和支架置入成功处理了闭塞情况。该介入治疗恢复了通过IVC进入右心房的静脉血流,并维持了通过导管的透析通路。该病例凸显了透析患者CVS/CVO管理的复杂性,尤其是血管透析通路内存在滤器的情况。
